Abstract

Continuous flow reactors have seldom been employed in investigations concerning 5-hydroxymethylfurfural (HMF) oxidation reactions. The root cause lies in the fact that, at atmospheric pressure, the solution exhibits a rather low oxygen content. In this research, we present a Ru-loaded manganese oxide octahedral molecular sieve (OMS-2) catalyst. Remarkably, this catalyst has exhibited the ability to achieve a 100 % conversion rate of HMF and attain a 94.5 % yield of FDCA under ambient air conditions within a continuous flow reactor. This can be mainly attributed to the superior oxygen adsorption and activation capacity of 0.05Ru-OMS-2. Thanks to this, it exhibits good performance even under hypoxic conditions. The combined results of EPR and XPS clearly showed that the Ru in the catalyst not only boosts the adsorption and transformation of O₂ but also weakens the Mn-O bond in the carrier, thus enhancing the activity of lattice oxygen.

期刊介绍： Applied Catalysis A: General publishes original papers on all aspects of catalysis of basic and practical interest to chemical scientists in both industrial and academic fields, with an emphasis onnew understanding of catalysts and catalytic reactions, new catalytic materials, new techniques, and new processes, especially those that have potential practical implications. Papers that report results of a thorough study or optimization of systems or processes that are well understood, widely studied, or minor variations of known ones are discouraged. Authors should include statements in a separate section "Justification for Publication" of how the manuscript fits the scope of the journal in the cover letter to the editors. Submissions without such justification will be rejected without review.
